Role of 18F-FDG PET/CT in pre and post treatment evaluation in head and neck carcinoma

Figure 3 Positron emission tomography/computed tomography for detection of mandibular invasion. A T4a floor of mouth squamous cell carcinoma (white arrow) with through-and-through involvement (red arrow) of the anterior mandible is demonstrated on axial contrast-enhanced computed tomography (CT) (A: Soft tissue window; B: Bone window), axial contrast-enhanced magnetic resonance imaging (C: T1WI; D: Post contrast enhanced T1WI with fat saturation), and positron emission tomography/CT (E: Axial; F: Sagittal).
